Patent DE-3910106-A1 (DE)
Inventor: SWOBODA HELLMUTH
IPC: E04B1/19
Filed: 1989-03-29
Abstract: To connect the individual bars (2) and supports (3), if any are present, of a framework structure, connectors having in a customary manner connector openings (4) and connector projections (5) are provided. In order that the connection process and also the detachment of the connection can be carried out as simply and quickly as possible and nevertheless a secure and firm connection can be obtained, retaining pins (6) which can be laterally deflected counter to a restoring force are provided inside the particular connector opening (4), within the clear cross-section thereof. The connector projection (5) which fits into the connector opening (4) has a sloping face (7) or tip which, on insertion, impinges on and moves apart these retaining pins (6) and, adjoining said oblique face or tip, an aperture (8) which recedes radially with respect to the largest cross-section of the connector projection (5) and into which the retaining pins (6) can thus spring back again, with the result that the first loose connection is already made. Adjacent to this aperture (8) in the circumferential direction there are provided regions (9) which, on relative rotation of the connector projection (5), deflect the retaining pins (6) in turn radially as far as the outer dimension of the connector projection (5), so that the connector projection (5) can be very easily drawn out of the opening (4) again or, conversely, the opening (4) can be very easily withdrawn from the projection (5). To secure the play-endowed connection, there is furthermore provided in the region of the connector projection (5) a sliding or screw sleeve (11) which, in the connected position, can be adjusted and locked relative to the surface region adjacent to the connector joint, with the result that the connector projection (5) and especially the radial boundary (8a) of its aperture (8) is clamped against the retaining pin (6) counter to the insertion direction.

Title: Bearing for cylinder levers
Inventor: BEHMEL JOHANNES
IPC: B41F31/32
Filed: 1989-05-16
Abstract: The invention relates to a bearing for one or more cylinder levers which can be mounted centrally about a cylinder bearing, in particular in frames of printing units of printing machines. According to the invention, for this purpose each cylinder lever is provided at one end with a circular segment-like bearing part which has a flange-shaped projection and has a circular-cylindrical outer surface lying perpendicular to the longitudinal axis of the cylinder lever and an outer surface, which is parallel to said outer surface but faces away from it on the projection which can be mounted and guided in an annular groove arranged in a wall of the printing unit centrally relative to the axis of rotation of the stationary cylinder, and the inserted bearing part or parts of the cylinder lever or levers can be secured against axial displacement by a divided clamping ring. The advantage of this bearing consists, above all, in the fact that significantly simplified assembly and demounting of the cylinder levers and cylinders are possible between the walls of the printing unit and independently of one another. <IMAGE>

Title: High resolution absolute coder with movable coding carrier - uses scanning beam deflectable in coding carrier movement direction
Inventor: HETTLAGE ECKART DIPL ING
IPC: G01D5/347
Filed: 1989-06-29
Abstract: The movable coding carrier carries codes read-out by a scanning beam of an optical read-out device, with the code characterising the position of the carrier. The scanning beam (2) can be deflected in the movement direction of the coding carrier (6), and follows in a preset small region the movement of the code (7) just picked up by the scanning beam. The instantaneous position of the code carrier is determined from the position information and the deflection of the scanning beam.  On attaining a region boundary, the scanning beam is possibly adjusted in its search to the adjacent picked up code.  Pref. the sequential codes each characterise a position of a point of the individual codes. USE/ADVANTAGE - Spacecraft rotary mechanisms, without variations of fine steps, drift of absolute precision in economical design.

Title: Fixing sheets of plastics foil to roof of greenhouse - by elastically deformable sections which fit one in another
Inventor: REISINGER GERHARD DIPL ING
IPC: F16B5/06
Filed: 1989-07-28
Abstract: The roof of a greenhouse is formed from sheets of transparent plastics film. These sheets (10) are held under tension by devices which grip the edges of the sheet.

Title: Thermoforming film container plus tube - by mould tools which grip tube in tapered holes so that when vacuum thermoforming is completed some space allows film to cool round tube
Inventor: SCHENK BERND
IPC: B29C65/02
Filed: 1989-09-07
Abstract: A flexible thin-walled container with at least one film filling or emptying tube for liq. contents is produced by making the container from two adjacent extruded flat sheets of thermoplastic material, thermoforming them under vacuum, and welding them together when closing the thermoforming mould. Before the mould is closed the tube is positioned between the two flat sheets so that, when the mould is closed, the sheets are not only welded together round their edges but are also welded to the tube; the outer end of the tube remains free so that the thermoplastic material/film round it can be cooled in shape. ADVANTAGE - The filling/emptying tube is virtually positioned and welded at the same time as the two halves of the container and in the split line concerned. The method ensures that the film round the tube cools effectively before the mould is opened again, so that it does not adhere to the tube or to the mould.

Title: Compositing rubbish, esp. household rubbish, contg. organic material - comprises compositing followed by compression using clamp in closed container
IPC: C05F17/00
Filed: 1990-06-12
Abstract: In composting rubbish, esp. household rubbish, contg. organic material, the rubbish is first composted and then compressed. Pref. composting is in clamps or in closed containers with addn. of air, and is stopped by drying when the more easily decomposable biological components have been broken down.
